They are tiny and at home in many freshwaters: water fleas. The so-called daphnia are unique in that they react very sensitively to pollutants in the water. Researchers at the University of Bayreuth have therefore used these small crustaceans as a yardstick to investigate the pollution of freshwater ecosystems.

Just like humans and animals, plants also have to defend against bacterial infections.

According to the Federal Statistical Office, slightly more than half of Germany's acreage was used for agriculture in 2016. Farmers are using modern machinery and pesticides and fertilizers to increase yields. Studies confirm: More intensive farming is detrimental to the environment and above all threatens species diversity. But a meta-analysis now shows at what a cost for nature a bountiful harvest actually comes.

As part of its internationalization strategy, the Max Planck Society has established a new Max Planck Center in Great Britain: At the Max Planck-Bristol Center for Minimal Biology, researchers will construct artificial cytoskeletons, develop nano-scale molecular machines and thus study the necessary building blocks for life

Whether palm oil, cotton or soy: many raw materials from plants used in Germany for the production of cosmetics, textiles, biodiesel or animal feed have to be procured from abroad. But where do the raw materials come from and what are the environmental consequences? An international study led by the Institute for Ecological Economics at the Vienna University of Economics and Business Administration (WU) provides answers. Researchers from the University of Bonn were also involved.

More than half of all their products, namely 60%, are to be sustainable in 2021, promises German sporting goods manufacturer Adidas. This will be achieved by using recycled polyester - e.g., from plastic waste collected from beaches - and reused cotton as well as by delisting animal furs. The brand also already has vegan shoes in its range. A real innovation, however, is what the group will exclusively launch with three other fashion companies worldwide this year: Shoes made of a mushroom mesh instead of leather.

A great start to 2021: After the launch of bioökonomie.de as an online portal in 2016, the information platform has now undergone a comprehensive relaunch. The implementation of a contemporary design, an optimized navigation structure and new functionalities for the diverse content were the main focus.

Modern high-yielding varieties of grain and other food crops are true miracles of productivity. Through breeding, they have been optimized to deliver maximum yields under typical growing conditions. But the most widely used method of hybrid breeding has also led to a depletion of the genetic variability of these varieties. As a result, today's hybrid varieties are often poorly able to adapt to changing environmental conditions, such as those already occurring due to climate change.
